GMC Denali XT Concept Preview – Chicago Auto Show: Remember the El Camino? A pickup based on a car, the El Camino lasted for years until it was finally cancelled in the mid 80s. Yet the basic concept has lived on in Australia, where these “utes” are quite popular, especially GM’s Holden Ute, based on the Commodore sedan. Now, let’s take this to a logical conclusion, shall we? GM is going to import the Holden Commodore and rebadge it as a Pontiac G8. The new Chevrolet Camaro is based on the same platform. So is it much of a stretch that an unquestionably handy ute version could find its way here? Maybe, if enough people are interested. Which brings us to the GMC Denali XT Concept.
